Can't access MainTabControl.Items parent from NTWindow

[franjcy]

Hi.

I'm trying access header tabs from a new window (NTWindow) created by indicator. I tried everything but i could find the correct way.

Inside the indicator I access tabs bythis way:

var chartWindow = Window.GetWindow(ChartControl.Parent) as Chart;
var tabs = chartWindow.MainTabControl.Items;

But inside addon it cant be accessed.

I tried also passing a parameter from indicator chart with actual chart but nothing works. Also with Owner methods.

Hi franjcy,

Please put the code below in the OnStateChange() function:

if (State == State.Historical) {
  if (isCharting) ChartControl.Dispatcher.InvokeAsync(() => {
      var chartWindow = Window.GetWindow(ChartControl.Parent) as Chart;
      var tabs = chartWindow.MainTabControl.Items;
   
      foreach ( TabItem tab in tabs ) {
          Print(tab.Header.ToString());
      }
  });
}

Regards,
William

Class of type NTWindow doesn't have OnStateChange() function.

Hi franjcy,

We have just created an indicator file. When pressing F5, it displays the NT window, and when pressing the button inside the NT window, it displays the header tabs.

Please refer to the attached file below.

Thanks for your contribution but it doesn't do what I need.
In your example, you're creating a new tabControl on the NTWindow and then reading the tabs.
What I need is, from a init window with charts in tabs, open a popup window (NTwindow) with a button and read the previous tabs from indicator was hosted.

franjcy,

You need to declare a global variable for the chart so that it can be accessed anywhere in your code. In this example, we used "chartWindow" (line 33). Then, you need to initialize it (see line 73).

Once initialized, you can use it throughout your code.

Please refer to the attached file below.
